Modern tool grinding machine design is very compact, machine parts and can add components to increase the risk of collision in the limited space of the machine, with precision machine model programming system to ensure the reliability of processing. NUMROTO the new version 3.5.1 optimizes the machine model and crash test functions, existing NUMROTO systems can be upgraded to the new version.

NUMROTO programming system has been available for more than 20 years, is now widely used in the world more than 2500 tool grinder. Due to the wide range of tools that can be processed by the software, it is possible to independently develop grinding programs and test collision safety on tool grinders and is selected by tool manufacturers.

With the continuous development of computer performance, the entire tool grinder and grinding process can be simulated with precision. Today, the vast majority of machine tools that use NUMROTO are equipped with three-dimensional simulations. Due to the application of 3D-CAD technology, the structural design of modern tool grinding machines is more compact, and the internal space of the machine must be optimized to be suitable for grinding tools of various external dimensions.

Even more difficult is the machine tool accessories usually can only be used to process certain tools or procedures, thus hindering other processing procedures. Due to the presence of these obstacles, the programming system must constantly calculate the grinding path to prevent collisions, which requires an accurate and realistic model of the machine tool. NUMROTO version 3.5.1 is equipped with an easy-to-use machine tool model, thus ensuring that the machine tool model on the computer is consistent with the real machine tool movement.

Today, this tool grinder basic model is used in the traditional tool grinding programming system. The machine tools are often equipped with some machine tool components, such as support frame, tail seat, mobile tool holder, special chuck for sintering castings or blades, dressing unit, passivation device and high frequency spindle. Fixed installed machine components, such as dressing units or high-frequency spindles, are selected with one click from the list of MUNROTO machine components, and these accessories are always visible on the machine model until the selection is canceled. For movable mechanical accessories like the support frame, the motion state has been edited with the corresponding parameters. The position-variable machine tool component can be held in a rest position during one machining step and be present in a working position during a subsequent machining step. These are accessories that use electric, hydraulic and pneumatic drive units. Similar accessories are activated by corresponding CNC commands. What is complicated in the model is that the axes control the movement of the machine tool components, such as moving the center frame to the specified position and exiting the specified position.

An addable component can be mounted to each machine part. The pressing device is installed on the mobile support frame, the guide sleeve is installed on the mobile center frame, and the components can be added in various shapes and sizes. If the machine tool needs to re-select other tool applications, only need to easily click the mouse in the NUMROTO to select other sizes of add-on components.

Both machine parts and addable components are stored in the NUMROTO database, so database backups are also possible. Due to the unlimited range of options, even very complex machine details can be displayed very realistically.

Since the machine model is integrated into the programming system, the program can be subjected to a detailed crash safety test before the newly generated tool program is used on the tool grinder. Collision tests run at high resolution to detect collisions even between very small components.
